Many audio systems have temporary device needs from time to time. For example, a teacher in a specific classroom in a school may only occasionally need to use a microphone or plug in a DVD player or a television. A meeting room in a hotel conference center may need a large number of microphones for a panel discussion, but only rarely. Instead of purchasing and installing the appropriate RADs to service all of these needs in all of these rooms, wouldn't it be much more cost-effective to have just a few of the needed RADs installed on, say, a rollable A/V cart that can be used when needed? The answer is, of course, YES!
So how can you accomplish this RAD portability in a HAL System? You do so by installing one or more RADX devices (which are less expensive than other RADs) in the rooms needing certain audio functionality only occasionally. You can think of the RADX as an extension cord. You simply roll the cart (if that's what you're using) into the room and connect the RAD on the cart to the RADX in the wall.
warning! The port to which the RADX is connected MUST be configured for a specific kind of RAD – and you can only plug in that type of RAD. In other words, you'll need a RADX for each type of RAD you plan to use as a portable device (in each specific location).
tip: Because a RADX must be configured for a specific RAD model, we recommend that you label each RADX in your system with the RAD model it can accept.
note: The RADX has an XLR-style 8P8C modular jack in it—to help the audio guy distinguish between the RADX and a standard CAT 5 Ethernet connection in the wall.
